Pre-Operation Checks - IVT GCHS-45 Manuel D'instructions

Instruction manual
Installing guide bar (7) and saw chain (6)
1. Place the machine on a level surface.
2. Make sure chain break initiator (9) is into
disengaged position, by pulling the chain break initiator
EN
(9) toward the rear handle (1). [F5]
3. Unscrew the fastening nuts (19), with the help of
the multi-purpose spanner (28) and remove the casing
(4). [F6]
4. Turn the chain tension bolt (23) counter-clockwise
until the end of the screw.
5. Mount the guide bar (7) onto the main unit of the
machine so that the positioning pins (22) fit into the
guide bar slot (20). [F7]
6. Mount the saw chain (6) on the guide bar (7),
paying attention to the direction of the teeth.
7. Slip the saw chain (6) around the chain wheel (21).
8. Replace the casing (4) in its position.
9. Tighten the fastening nuts (19) by hand.
10. Check the proper position of the saw chain (6), -
the saw chain (6) mustn't slip off the guide bar (7), and
tension the saw chain (6) properly.
WARNING! Do not use the chainsaw
before tensioning the saw chain (6).

PRE-OPERATION CHECKS

Checking the tension of the saw chain (6)
A loose saw chain (6) can easily derail or cause rapid
wear of itself and the guide bar (7). The tension of the
saw chain (6) should be checked frequently, particularly
before starting to operate, after the first cuts and
regularly throughout the work (every 10 minutes). The
working lifespan of a saw chain (6) depends on its
adequate lubrication and correct tension.
NOTE: during the first cuts, when the machine is still new,
the saw chain (6) will loosen quite frequently, but this is
normal during the breaking-in period of a new tool.
ATTENTION! Never leave the saw chain (6) loose as
it may come off the guide bar (7) while cutting. If the
saw chain (6) is too tight, it could cause overheating
and damages.
To check the tension of the saw chain (6):
∙ Pull it slightly aside from the center line of the guide
bar (7) and then release it. Saw chain (6) is correctly
tensioned if it can be lifted up in the middle by max.
3 mm; moreover, it must return to its original position
under its own elasticity. [F8]
To adjust the tension of the saw chain (6):
1. Place the machine on a level surface.
2. Loosen the fastening nuts (19) with the help of the
multi-purpose spanner (28).
3. Hold nose of guide bar (7) (use gloves!) up and
adjust the tension of the saw chain (6) with the chain
tension bolt (23), (CLOCKWISE to increase tension,
COUNTERCLOCKWISE to decrease tension). [F9]
4. Tighten the fastening nuts (19) with the help of the
multi-purpose spanner (28) securely, always holding the
nose of guide bar (7) upwards.
5. Check for the correct tension again.
Checking the oil level
Prior to each use of the machine, as well as after every
10 minutes of operation it is necessary to perform a
check of oil level in the oil tank.
1. Place the machine on its side on a flat surface.
2. Clean the surface around the oil tank plug (17) and
unscrew it.
3. Insert the clean rod into the mouth of the oil tank:
if the oil level doesn't reach 2/3 of the rod's length, add
oil into the tank.
4. Replace the oil tank plug (17).
ATTENTION! Whenever you refill the fuel tank with
fuel, you must also top up the level of oil in the oil
tank. It is recommended to use standard chain oil.
CAUTION! In order to avoid damage
to the machine, use only oil of
recommended
circumstances should old or recycled
oil be used. The use of unauthorized
oil forfeits the right to present
guarantee claims.
Checking the fuel level
Prior to each use of the machine it is necessary to
perform a check of the fuel level in the fuel tank.
The correct fuel for the two-stroke engine of this
machine is gasoline-oil mixture: mix a regular
gasoline (leaded or unleaded, alcohol-free) and a
quality-proven motor oil for oil cooled 2 cycle engines.
Recommended mixing ratio (Gasoline:Oil): 25:1
12
grade. Under no
